  • the vibrations of the cutting edge preferably have a horizontal component parallel to a cutting edge of the cutting edge (or along the z-direction or along the longitudinal direction of the cutting edge) and/or a component vertical to the cutting edge of the cutting edge (or along the y-direction) and/or a horizontal one Component perpendicular to the cutting edge edge (or along the x-direction or conveying direction).
  • the vibration exciter generates vibrations of the cutting edge with an amplitude in a range between 0.1 millimeters and 5 millimeters, particularly preferably in a range between 0.25 millimeters and 3 millimeters in the z-direction (or longitudinal direction).
  • Excitation in the z direction is preferred if the impurities on the cutting edge are to migrate laterally. This direction of excitation is preferably superimposed on a further excitation in the y direction, since this prevents the laterally migrating impurities from getting caught on nicks in the cutting edge edge.
  • exclusive excitation in the z-direction e.g.
  • the vibration exciter preferably generates vibrations of the cutting edge with a frequency in the range from 1 Hz to 500 Hz, preferably in the range from 10 Hz to 100 Hz.
  • the vibration exciter preferably causes the cutting edge to vibrate in such a way that a speed at which the impurities are moved over a cutting edge of the cutting edge is between 0.05 m/s to 0.5 m/s and in particular approximately 0.1 m/s.

  • a method for producing a bulk material sorting system as described above includes the steps of providing the bulk material separator and the sorting device, as well as providing the clearing device, the cutting edge being connected to the vibration exciter of the clearing device.
  • the clearing device (1) comprises a cutting edge (10) for a bulk material sorting system (2), which is equipped with a drive (12) in the form of a vibration exciter, which causes the cutting edge to vibrate.
  • a drive (12) in the form of a vibration exciter, which causes the cutting edge to vibrate.
  • the cutting edge is spring-mounted (13).
  • FIG. 1 The clearing device (1) according to the invention is shown installed in an eddy current separator.
  • the cutting edge (10) which separates the residue mass flow from the concentrate mass flow, is mounted on springs (13) and is caused to vibrate by the vibration exciter (12).
  • FIG. 2 A corresponding embodiment for drum magnetic separators is in Fig. 2 sketched.
  • magnetizable material (4) is separated from non-magnetizable material (5) via a magnetic drum into a magnetic concentrate (7) and a residue (6).

  • the cutting edge edge (11) is cleared of any impurities hanging above it, for example textiles (20), cords (21) and wires (22), by causing the cutting edge (10) to vibrate in such a way that the impurities are essentially horizontal move over the cutting edge edge (11) (z direction).
  • the vibrations of the cutting edge triggered for this purpose have, as in Figures 3a and 3b shown, a horizontal component parallel to the cutting edge (11) (z direction), and/or a component vertical to the cutting edge (11) (y direction) and/or a horizontal component perpendicular to the cutting edge (11) (x direction) .

  • a vibration exciter (12) which is designed as a knocker ( Figures 5a and 5b ). This knocks periodically and essentially parallel to the z-direction against the cutting edge, whereby the cutting edge edge (11) slides from the starting position under the impurities hanging above it by a short distance (e.g. 1 mm) under the impurities particles and then springs back (slower) into the starting position , whereby the impurity particles are taken along by the spring-back cutting edge (11).
  • a short distance e.g. 1 mm
  • This asymmetrical horizontal movement of the cutting edge (11) creates a "slip", which causes the impurities hanging over the cutting edge (11) to gradually “slide” on the cutting edge (11) in the direction of the knocking point, for example by one millimeter each horizontal knock pulse.
  • FIG. 4 A particularly preferred embodiment is in Fig. 4 shown.
  • the cutting edge (10) is spring-mounted (13).

  • the cutting edge is preferably resiliently supported by elastically deformable plastic elements (13) (“rubber buffers”).
  • vibration exciters In principle, all devices that are able to cause the cutting edge (11) to vibrate can be used as vibration exciters.
  • the preferred installation of the vibration exciter is directly on the cutting edge and in particular near the center of gravity of the cutting edge.

  • This roof-shaped cutting edge (10) can be supported directly on the sorting cutting edge (9) ( Fig. 6a ), or it can be supported on the carriage on which the cutting edge is mounted for distance adjustment.
  • the roof-shaped separating sheath (10) can also be installed in a non-contact manner ("floating") above the sorter cutting blade (9) and can be supported on the machine housing or the steel structure in the system ( Fig. 6b ).
  • the roof-shaped cutting blade (10) would be guided, for example, through openings in the device wall of the sorting device and supported outside the sorting space by means of spring assemblies (13).
